Motorcycle with an exhaust gas sensor

摘要

The invention positions an exhaust gas sensor in such a manner that a protective cover is not required, collisions and water bursts due to flying stones are avoided as much as possible, where maintenance work is straightforward, and where available space is effectively utilized. To achieve this, an exhaust gas sensor 29 is fitted to an upper side wall of an exhaust pipe 26 at a position forward from a right projection 14a of a crank case 14 and facing out from a right side surface 15a of a cylinder block 15.
